As we deal with the aftermath of our country’s adventures in Afghanistan and Iraq as it seems we are preparing to do battle with ISIS, it behooves us to seek out the aftermath of those who fought those wars. War is never easy on those who fight it, regardless of the reasons they have for leaving their homes and their families and going off to some godforsaken place to kill other human beings. We often take that part of our armed forces for granted.

Chris Kyle (Cooper), a proud Texan and would-be cowboy, goes because he feels that after 9-11, it is his duty to protect a country that he loves. He leaves behind a wife Taya (Miller), a strong woman of no uncertain opinions who eventually falls for the burly Texan despite having exceedingly low expectations when first they met. He joins the Navy SEALs mainly because he believes them to be the toughest SOBs in the military.

Kyle proves to be a gifted sharpshooter who is perfect for sniper duty. His first action requires him to make an agonizing decision when it seems that a young boy is getting ready to hurl an explosive at an American convoy in full sight of his mother, who handed him the device. He waits until the last possible second, before it becomes apparent that his intentions are to blow up the convoy; then Kyle shoots him dead, and then his mother for good measure when it appears she’s going to finish the job her son was unable to. Far from being a moment of triumph, it deeply affects the young SEAL deeply. When he sees a terrorist (Hamada) put a drill through the head of a child while his parents watch, he decries the Iraqis as savages and it’s hard not to argue with him.

Kyle goes through four tours, and each time he returns home as Taya puts it, he’s not really there. He’s nervous, jumpy, living very much inside his head while Taya tries desperately to reach him, to get her husband back. By now Kyle is also a dad, and while he goes through the motions of being a father and assures VA psychotherapists as well as his immediate family that everything is fine, everything clearly is not. He only seems to be whole in country.

As he piles up the confirmed kills, he gets the nickname of Legend which at first makes him uncomfortable but eventually he grows to accept. It is a mark of the respect in which his peers hold him as he becomes the most lethal sniper in U.S. military history, for all the lives of American military men he saves with his unerring aim and precise shots. There is however a counterpart within the ranks of the enemy, one known as Mustafa (Sheik) who is in many ways a mirror image of Kyle – a family man, one obsessed by his work and absolutely deadly. Somehow Kyle needs to survive his tours and come back to his wife and family – a whole man.

Clint Eastwood has become over the years a great American film director and although he has had his share of missteps (cough Jersey Boys cough cough) his consistency has been as good as any. In a lot of ways this is going to be counted as one of his best works ever, although it is steeped in controversy more because of the subject matter than anything else.

There are those who have decried the film because in their minds it glorifies an individual who shouldn’t be glorified. Many have pointed out that the real Kyle, on whose autobiography this is based, consistently identified Muslims as savages (which he does in the film on one occasion) and has been labeled a racist because of it. He has also been taken to task for exaggerations or making up incidents out of whole cloth.

These are two separate issues and on the first, I can only say that it was common for veterans of war to dehumanize those they fought against. It is one way for the psyche to cope with having to kill other human beings. If they aren’t human, if they’re savages, it makes it easier to justify what you’re doing. Thinking that way may not necessarily be politically correct but it’s at least understandable.

The other can also be looked upon as something of a Texas thing. Now, making up a story in which former governor and ex-Navy SEAL himself Jesse Ventura was rude and insulting to fellow SEALs who were mourning a friend and getting clocked by Kyle is wrong and Ventura – who has been excoriated for doing so – has every right to defend his reputation, even if it means suing the widow of the man responsible because she is after all profiting from the story in a matter of speaking, since the story is a part of his best-selling book. While I give veterans a good deal of leeway in their behaviors, they are nonetheless responsible for their actions when they return home and are liable for the consequences of those actions.

That said, I don’t think this film glorifies war at all or this one in particular – at one point, at a soldier’s funeral, an unidentified woman who I assume is the soldier’s mother reads a handwritten eulogy condemning the war – but rather tries to give us insight into those who fought it. For me, the most compelling material is when Kyle is home, struggling to be home and be present with his family. It takes a good deal of time for him to finally want to be home, to finally let go of his feeling of duty and to get past his need to be a hero which the real Kyle was often accused of and Eastwood seems to agree was part of the man’s psychological make-up.

Cooper, who added 40 pounds for the role, really inhabits the role of Kyle, who actually resembled the late wrestler Chris Benoit in reality. It’s a mesmerizing performance certainly worthy of the Oscar nomination he received. Cooper’s Kyle moves from a fairly normal aw-shucks cowboy to a heroic sniper in the field to a terse, uncommunicative stone wall of a man at home. It’s a brilliant performance that shouldn’t be missed.

Sienna Cooper’s performance as Taya is also flawless. It’s so good I wish the script and Eastwood would have devoted more time to her; at times she almost becomes one-dimensional because she’s trying to convince her husband to leave the war behind and be home. How she kept her family together, how she weathered those times when he was home and not with her (it must have been heartbreaking) would have added more nuance to the film overall. I’d have gladly sacrificed some of the battle sequences of Kyle in country for that.

About those battle sequences; they can be pretty intense and for those who might be sensitive to such things, you should be forewarned that there are scenes that are quite disturbing. However, the rest of us will find them, as I did, absolutely mesmerizing and keep you on the edge of your seat, as I was.

I don’t know why we need our heroes to be absolutely perfect. Nobody is, and Chris Kyle certainly wasn’t. I don’t know that I agree with all of his views or approve of some of the things he said. That doesn’t mean he wasn’t a great soldier, an expert marksman or a hero for saving the lives of hundreds and perhaps thousands of American troops. I do believe that for most people, how you feel about the war will color your perceptions of this film. The conservative right are hailing the movie as a masterpiece (which it isn’t – Unforgiven was far better) while the progressive left are decrying it as propaganda which it also isn’t. What it is when you get right down to it is a terrific movie about war itself, about surviving it not only physically but emotionally and mentally as well, and how hard it can be to come home when the tour of duty ends.

REASONS TO GO: Cooper is brilliant. Realistic and often heart-stopping battle sequences. Admirably allows viewers to make their own minds up.REASONS TO STAY: Occasionally too intense for the sensitive. I would have liked to have gotten a little deeper into the mind of Taya.FAMILY VALUES: Much gunfire and war violence, some of it quite disturbing. There’s also plenty of colorful language with some sexual references involved.TRIVIAL PURSUIT: The real Chris Kyle and the real Marcus Luttrell of Lone Survivor fame actually met in SEAL school and became close friends which they remained for the rest of Kyle’s life.CRITICAL MASS: As of 2/2/15: Rotten Tomatoes: 73% positive reviews. Metacritic: 72/100.COMPARISON SHOPPING:Stop-LossFINAL RATING: 8/10NEXT:A Most Violent Year
